Drop guava runtime dependency

[simon04]

Some fuctionality is provided by Java 8, the remaining parts can easily be rewritten.

In general i agree with this, but this PR has to much modifications, changes formatting of lines which are not affected, error messages are different, tests are failing.

If you are trying to improve this i can accept tis.

[simon04]

I just fixed the checkstyle issues (which caused the tests to fail). There shouldn't be any unrelated formatting changes, though.
